Pneumatic diaphragm pump
>Pneumatic diaphragm pump product introduction
>BQ series pneumatic diaphragm pump is mainly used for mine tunnel development, shaft shaft construction, mining working face tank and sewage discharge around various equipment, and underground cave chambers Engineering drainage, sewage discharge, sand discharge, mud discharge, mine tunnel whitening application, etc.
>Functional features of pneumatic diaphragm pump
>Pneumatic diaphragm pump uses air flow to push the valve core to reciprocate, so that the pressure air enters the left and right air chambers alternately, causing it to push the diaphragm to reciprocate and make the working chamber A pressure difference is generated inside to achieve the purpose of water absorption and drainage. It is small in size, light in weight, and does not require a foundation. It can be used as a mobile pump without lubrication. The main valve has no special requirements for the air source and can be started by self-priming.

The company relies on the strength and advantages of scientific research institutes such as the 716th Research Institute of China Shipbuilding Industry Corporation, China University of Mining and Technology, Nanjing Design Institute, Jinan Design Institute, Shandong University of Science and Technology, Beijing Coal School, etc., and aims at a high starting point, high quality, and high-tech content. , committed to the development, production, sales and after-sales service of mechanical and electrical products that are safe, energy-saving, efficient and environmentally friendly for coal mines.
>The company now has ten series and more than forty varieties of products. The main products are: belt feeder, reciprocating feeder, wet concrete spraying machine, roller tank ear, broken belt catcher for belt conveyor, pressure air self-rescue device, pneumatic car arrester, pneumatic horizontal brake, Pneumatic vehicle blocking beam, inclined lane anti-car racing device (one slope and three gears), belt conveyor conveyor belt automatic deviation correction device, shaft skip quantitative bucket loading equipment, pressureless damper, composite wear-resistant steel plate, pin tooth operating complete set of equipment, Communication audible and visual annunciators, verbal audible and visual alarms, belt conveyor comprehensive protection devices, mining damper automatic control devices, mining switch control devices, mining automatic water sprinkler and dust suppression devices, mining sports car protection devices, etc. Among them, there are many products that have obtained national patents, and they have obtained patent funds from the Municipal Science and Technology Commission and the District Committee, and three scientific research projects have produced huge benefits.
>The company is willing to pursue zero-defect product quality with high-quality and advanced products, perfect after-sales service, and the business philosophy that customers are always God. We sincerely invite new and old customers to visit us for guidance, negotiate cooperation, and create a win-win situation.
>Remove the ball, ring and ball seat
>②Remove the fluid cover
>③Remove the screws and diaphragm gasket
>④Remove the ring, be careful not to Scratch or scratch the surface of the connecting rod.
>． Replace damaged parts and grease the connecting rod (diaphragm rod) and ring with b lubricating oil.
>, reassemble in reverse order.
>9. Fault phenomena and solutions
>, output reduction, vortex or flow stop
>① Check the gas supply
>② Check the outlet hose
>⑧ Check whether the inlet hose is entangled or broken
>rq④ Check whether the pump is empty. If high-viscosity liquids are pumped, the size of the feed pipe must be at least as large as the diameter of the inlet thread of the pump
>. to ensure correct flow. The feed delivery hose must be of a type that will not be damaged and can withstand high vacuum
>⑤ Check the connections on the intake manifold and the feed and discharge pipes, these must have good air tightness< br/> >⑥ Check whether solid matter is stuck in the diaphragm chamber or ball seat area of the pump.
>. The pumped substance is ejected from the exhaust port
>① Check the rupture of the diaphragm
>② Check whether the diaphragm screw is tight
>. Bubbles appear in the pumped substance
br/> >① Check the connection of the feed pipe system
>② Check whether the ring between the feed pipe and the fluid cover is damaged
>⑧ Check whether the diaphragm screw is tight.
